Hi:I am using the ORCAD Capture - Allegro flow. I have a VertexIV FPGA, and lot of differentialpairs. To sucessfully routed the PCB, those differential pairs have to be swapped. I don't want pin-pin swap, since this is very easy to make mistakes. Does anybody have the ideahow can I get pair-pair swap in my design flow(with pair polarity) ? I cannot make manyhomogeneous parts at schmatics side since this is not my job, it seems to me once I got thisby device file, but rightnow I keep getting error message. It will be very thankful if anybodycan give a hint on this.Thank you in advance.
You are looking for 'function' swap which is well documented in the OrCAD and Allegro literature.
